i play a lot of stellaris great game with 150+ mods.
their is only a slight problem.... it's loading time you see it takes around 10 minutes to start the game

so what i do mostly is start up the game and tab back to web browser or a other game while the game loads in the background

this can be done more efficient, if i should run the game directly into the background.
(what i means with background is not automatic start up) no the background you have like alt tab.

anyone knows if this is possible?

it depends how many cpu cores youve got

8 cores.

1. Right-click on the program's EXE file.
2. Select CREATE SHORTCUT. It will either create a shortcut in that folder or tell you it needs to create it on the desktop.
3. Right-click the shortcut file and select PROPERTIES.
4. Change the RUN option to MINIMIZED.
5. Click OK.

You'll need to start the game using that shortcut file. If you start it through any other means it will start as normal.

Note that minimized programs may receive lower priority, so it might take even longer for the game to start.

it still force it to the foreground (but alt tab) go's much smoother now.
